BRICK-MOLD-SANDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 411,228, dated September 17, 1889.

- Application filed August '7, 1888. Serial No. 283,8Q6. (N0 model.)

T0 at whom it may concern.-

Be it known that I, GEORGE E. SMITH, of Kingston, in the county of Ulster and State of New York, have invented a new and Improved Briek-WIold-San din gMachin e, of which the following is a full, clear, and exact description.

This invention relates to a machine for sanding brick-molds, and has for its object to provide a brick-mold-sanding machine by means of which the molds may be regularly fed forward to the press and will at the same time be effectively sanded.

The invention consists in a machine for sanding brick-molds and feeding them forward to the press, constructed and arranged as hereinafter described and claimed.

Reference is to behad to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the machine. Fig. 2 is a vertical section on the line w 00, Fig. 1. Fig. 3 is a vertical section on the line y y, Fig. 1. Fig. 4t is a vertical section on the line .2 2, Fig. 1, looking from the opposite end to that in Fig. 3, with molds removed; and Fig. 5 represents the sandingmachine connected to a brick-press.

In carrying out this invention a rotary cylinder or sand-box 1, for containing the sand, The frame 2 is constructed with an incline or feeding-chute 3 at one of its upper corners for the brick- .molds, formed of inclined slats 3, and i a curved inclined way or chute 4 atthe diagonally-opposite lower corner. The lower end of feeding-chute 3 lies adjacent to the periphery of cylinder 1 and is provided with pins 5 011 the slats 3', against which pins rests the lowest mold of the molds 6 lying on the feedchute 3. The cylinder 1 is formed with a series of openings 7 in. its periphery for the discharge of the sand in sanding the molds. The mouths of the openings 7, which correspond in size with the open side of the molds, pass through ways 8, on which the edges of the molds 6 rest, which. ways are provided each side of the openings 7 with guide-strips 8,which extend across the chute 4t. Retain .ing-straps 9 are also pr0vided,which hold the molds 6 in place over the opening 7 when being carried about the rotating cylinder 1 and sanded. Pins 10 extend in line with one side of the openings 7, forming a continuation of one of the guide-strips 8.

10' is a retaining strap or bar extending across chute 3 to hold the last mold at the bottom but one in place as the bottom mold is taken off by pins 10 from pins 5.. In the revolution of the cylinder 1 the pins 10 are brought around beneath the lower end of feedchute 3 and break joint with and pass between the pins 5.

At the lower end of curved chute 4 in the end wall of frame 2 is located an opening 11, provided with a discharge-chute 12, and on the opposite side of opening 11 from the foot of curved chute 1 is located a stop and guidestrip 13, at which point the space between the chute 4 and the periphery of the cylinder 1 g is sufficient to allow the guide-strips 8 to pass over molds 6, held by the strip 13. A curved strip 14: extends from the side of frame 2 at its top adjacent to the lower end of chute 3 diagonally over the cylinder 1 to the adjacent side 15 of the frame 2, adjacent to the line of travel of the openings 7 in the rotating cylinder.

The rotary cylinder 1 is provided with a the openings 7 of the cylinder across and of such a height as to sweep the curved chute 4E.

The frame 2 is located adjacent to the wellknown brick-machine, the discharge-chute 12 delivering the sanded molds to the brick-Ina chine, (in their usual place.)

The rotary cylinder 1. may be driven by any suitable mechanism,the mechanisinpreferably being connected with the press, so that the sandingmachine will work in unison therewith. As here shown, a lever 17 is pivoted at one end to one side of the frame 2 and extends across the latter through a slot 18 in the opposite side.

To the projecting end of lever 17 is pivoted a lever 19, having a forked end 20, which in the backward movement of lever 17 slides over one of a series of pins 21, projecting laterally from a disk 22 on the projecting series of diagonal strips 16, extending from I shaft 23 of cylinder 1, and has its forked end a 20 brought into engagement with said pin 21,

and in the forward movement of lever 17 is moved forward, thereby rotating the disk 22 until the lever 17 has reached the end of its forward stroke, when the lever 17 and its forked end 20 are again drawn backward by lever 17, as before, and the succeeding pin 21 engaged. By means of a succession of such movements the cylinder 1 is rotated. The

outer end of lever 17 is connected in any suitable manner with the brick-press machine, so as to be operated in unison with the pressin g of the bricks.

In the operation of the brick-mold-sanding machine a number of molds 6 are placed in the feed-chute 3, the lowest mold resting against the pins 5. A mold 6 may also he slid over each of the openings 7 beneath the retaining-straps 9, the open side of the mold facing the opening, with its edges resting be: tween the guide-strips 8. Upon the rotary sand-box or cylinder 1 being rotated, the pins 10, adjacent to one of the openings 7, are brought around beneath the lower end of chute 3 and pass up between the pins 5, lifting off therefrom the lowest mold 6. As the bottom mold G is lifted off of pins 5, the succeeding I old 6 is pushed down onto the pins 5 by the weight of the molds 6 resting above it, the strap 10 preventing the succeedin g mold from being drawn off from the chute as the bottom mold is carried away by the rotation of the cylinder. As the mold removed from the chute 3 and resting on the pins 10 and the way 8 is carried forward by the rotating cylinder, its outer end bears against the diagonal strip 14, and the mold is gradually pressed forward thereby across the cylinder, pushing the mold held by the straps 9 off from the opening 7, and being pushed in turn by strip 14 over the opening 7. When the two molds thus described have reached, in the rotation of the cylinder 1, a point in line with the top of chute 4, the outer mold 6, resting between the guide-strips 8', will be carried down the chute 4, and upon reaching the bottom of the chute will be caught by the stop and guide-strip 13 and tinued, the mold 6 being forced forward in a continuous line between the guide-strips 8 and through the chute 12, a sanded mold being moved into the press as fast as a preceding mold is filled, pressed, and removed.

In Fig. 5 the brick-mold-sanding machine is shown connected with a brick-press. The lever 17 is pivotally connected by a lever 24,

pivoted to a brick-machine 25, to the vertically-reciprocating rod 26, having the press 27 at its lower end. By means of this connection the sanding-machine will be operated by the brick-machine, so that as the rod 26 is raised a mold 6 beneath the press will be fed forward and another mold 6 shoved into place beneath the press by the action of the sanding-machine in feeding the molds 6 forward from chute 12. In this way the brickmachine and sanding-machine will act together, a mold being fed under the press during every upward stroke of the rod 26. In this way any number of molds will be thoroughly sanded and carried forward to the press in an expeditious and efficient manner.

While I have set forth a specific construction of parts, I do not desire to limit myself thereto, as they may be varied without departing from the essential features of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
